Bollard



FIG. 1 is a front view of a bollard according to our new design;

FIG. 2 is a side view of the bollard of FIG. 1;

FIG. 3 is a top view of the bollard of FIG. 1;

FIG. 4 is a front perspective view of the bollard of FIG. 1; and,

FIG. 5 is a rear perspective view of the bollard of FIG. 1.

Contrast in materials is shown by using stippling to differentiate between areas of differing material. The support legs of the bollard are shown in broken lines for illustrative purposes only and form no part of the claimed design. 

I claim the ornamental design for a bollard, as shown and described.
